2025-01-27linux-container: Ignore EPERM when attempting to mount /sys.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/61690>. Until now, this would work: guix shell --no-cwd -CWP -- guix shell -C coreutils -- ls -R /home … but this would not: $ guix shell --no-cwd -CWPN -- guix shell -C coreutils -- ls -R /home guix shell: error: mount: mount "none" on "/tmp/guix-directory.Wnc2OI/sys": Operation not permitted This is annoying and hardly understandable. Since we already disable /sys mounts when sharing the global network namespace is asked (as in ‘guix shell -CN‘), for the very same reason, we can just as well disable /sys mounts anytime it fails with EPERM. * gnu/build/linux-container.scm (mount-file-systems): Silently ignore EPERM when attempting to mount /sys.

2024-12-18system: Add /etc/subuid and /etc/subgid support.Giacomo Leidi
This commit adds a Guix System service to handle allocation of subuid and subgid requests. Users that don't care can just add themselves as a subid-range and don't need to specify anything but their user name. Users that care about specific ranges, such as possibly LXD, can specify a start and a count. * doc/guix.texi (Miscellaneous Services): Document it. * gnu/build/activation.scm (activate-subuids+subgids): New variable. * gnu/local.mk: Add gnu/tests/shadow.scm. * gnu/system/accounts.scm (sexp->subid-range): New variable. * gnu/system/shadow.scm (%root-subid): New variable; (subids-configuration): new record; (subid-range->gexp): new variable; (assert-valid-subids): new variable; (delete-duplicate-ranges): new variable; (subids-activation): new variable; (subids-extension): new record; (append-subid-ranges): new variable; (subids-extension-merge): new variable; (subids-service-type): new variable. * gnu/tests/shadow.scm (subids): New system test.

2024-12-18accounts: Add /etc/subid and /etc/subgid allocation logic.Giacomo Leidi
This commit adds allocation logic for subid ranges. Subid ranges are ranges of contiguous subids that are mapped to a user in the host system. This patch implements a flexible allocation algorithm allowing users that do not want (or need) to specify details of the subid ranges that they are requesting to avoid doing so, while upholding requests of users that need to have specific ranges. * gnu/build/accounts.scm (%subordinate-id-min): New variable; (%subordinate-id-max): new variable; (%subordinate-id-count): new variable; (subordinate-id?): new variable; (&subordinate-id-error): new variable; (&subordinate-id-overflow-error): new variable; (&illegal-subid-range-error): new variable; (&specific-subid-range-expected-error): new variable; (&generic-subid-range-expected-error): new variable; (within-interval?): new variable; (allocate-unused-range): new variable; (allocate-generic-range): new variable; (allocate-specific-range): new variable; (reserve-subids): new variable; (range->entry): new variable; (entry->range): new variable; (allocate-subids): new variable; (subuid+subgid-databases): new variable. * gnu/system/accounts.scm (subid-range-end): New variable; (subid-range-has-start?): new variable; (subid-range-less): new variable. * test/accounts.scm: Test them.

2024-12-18accounts: Add /etc/subuid and /etc/subgid support.Giacomo Leidi
This commit adds a new record type, <subid-entry> and serializers and deserializers for it in (gnu build accounts). Each instance of this record represents one line in either /etc/subuid or /etc/subgid. Since Shadow uses the same representation for both files, it should be ok if we do it as well. This commit adds also <subid-range>, a user facing representation of <subid-entry>. It is supposed to be usable directly in OS configurations. * gnu/build/accounts.scm (subid-entry): New record; (write-subgid): add serializer for subgids; (write-subuid): add serializer for subuids; (read-subgid): add serializer for subgids; (read-subuid): add serializer for subuids. * gnu/system/accounts.scm (subid-range): New record. * test/accounts.scm: Test them.

2024-11-11bootloader: grub: Remove hardcoded partition number for the Hurd.Janneke Nieuwenhuizen
This supports using another than the default DISK0 PART1 and using LABEL or UUID as root file-system specifier. It still defaults to DISK0 PART1 if the file-system cannot be found, i.e., lives only at the build side: A virtual machine/childhurd build. * gnu/build/file-systems.scm (%hurd-device-spec-regexp, %device-spec-regexp): New variables.

2024-11-03activation: Create directory with specified perms in ‘mkdir-p/perms’.Reepca Russelstein
There is currently a window of time between when the desired directory is created and when its permissions are changed. During this time, its permissions are restricted only by the umask. Of course, in the "directory already exists" case, this doesn't matter, but if the directory has been specifically deleted ahead of time so that it is created afresh, this is an unnecessary window. We can avoid this by passing the caller-provided BITS to 'mkdirat' when attempting to create the last directory. * gnu/build/activation.scm (mkdir-p/perms): Create target directory with BITS permissions.

2024-07-26file-systems: Allow specifying CIFS credentials in a file.vicvbcun
As files in the store and /etc/fstab are world readable, specifying the password in the file-system record is suboptimal. To mitigate this, `mount.cifs' supports reading `username', `password' and `domain' options from a file named by the `credentials' or `cred' option. * gnu/build/file-systems.scm (mount-file-system): Read mount options from the file specified via the `credentials' or `cred' option if specified.
