| | | | | | | | | | Previously, partitions of mdadm- or cryptsetup-produced block devices would not be returned by 'disk-partitions'. * gnu/build/file-systems.scm (disk-partitions)[last-character]: New procedure. [partition?]: Add 'name' parameter and rewrite. Adjust caller. * gnu/build/file-systems.scm (ENOENT-safe): Silently ignore ENOMEDIUM.
* file-systems: Always use (guix build syscalls).Ludovic Courtès2016-09-05

This fixes a bug whereby we would be truncating MOUNT-POINT if it already existed.
* build: file-systems: Allow for bind mounting regular files.David Thompson2015-08-08
| | | | | | * gnu/build/file-systems.scm (regular-file?): New procedure. (mount-file-system): Create a regular file instead of a directory when bind mounting a regular file.

| | | | | | | * gnu/build/file-systems.scm: Import (guix build syscalls) when 'mount' is not defined. * gnu/system.scm (operating-system-activation-script): Include (guix build syscalls) module in derivation.
* gnu: Make 'mount' interface in static Guile consistent with Guix API.David Thompson2015-06-19
| | | | | | | | | | Rather than expecting a pointer, the version of 'mount' in guile-static-stripped now takes a string for the 'options' argument, just like the 'mount' procedure in (guix build syscalls). * gnu/packages/patches/guile-linux-syscalls.patch (mount): Expect a string or #f for 'options' argument. * gnu/build/file-systems.scm (mount-file-system): Use new 'mount' interface.
* file-systems: Use a second 'mount' call for read-only bind mounts.Ludovic Courtès2015-04-20
| | | | | | | * gnu/build/file-systems.scm (MS_REMOUNT): New constant. (mount-file-system): Add 'flags' local variable. When FLAGS has MS_BIND & MS_RDONLY, call 'mount' with MS_REMOUNT. * gnu/services/base.scm (file-system-service) <start>: Likewise.
* linux-boot: Make /etc/mtab a symlink to /proc/self/mounts.宋文武2015-01-05
| | | | | | | | | | Fixes <http://bugs.gnu.org/19491>. * gnu/build/linux-boot.scm (mount-root-file-system): Make /root/etc/mtab a symlink to /proc/self/mounts. * gnu/build/file-systems.scm (mount-file-system): Don't update /etc/mtab. * guix/build/syscalls.scm (mount, umount): Have #:update-mtab? default to #f.
* file-systems: Always write the options field in /etc/mtab.Ludovic Courtès2014-11-20
| | | | | | | | * gnu/build/file-systems.scm (mount-file-system): When OPTIONS is false, write "rw" to /etc/mtab. This fixes a bug whereby 'remove-from-mtab' in (guix syscalls) would otherwise raise a 'match-error' because of the missing field. This affected file systems mounted from the initrd, such as devtmpfs, which has options == #f.
* linux-boot: Ask fsck for a progress bar.Ludovic Courtès2014-09-19
| | | | | * gnu/build/file-systems.scm (check-file-system): Pass '-C 0' to FSCK. Suggested by Mark H. Weaver.
