file-systems: Have the emergency REPL output to /dev/console.
This fixes a bug whereby all emergency REPL output would go to /dev/klog
and thus, each line would be prefixed by "[12324.432] shepherd[1]: ".

* gnu/build/file-systems.scm (check-file-system): Wrap 'start-repl' call
in 'with-output-to-file'.

Reported by Jan Nieuwenhuizen <janneke@gnu.org>.

* gnu/build/file-systems.scm (check-file-system): Call 'start-repl' only
if current-input-port passes 'isatty?'.
* gnu/services/shepherd.scm (shepherd-configuration-file): After
'for-each' expression, call 'redirect-port'.

file-systems: Always wait for devices to show up.
Previously, 'canonicalize-device-spec' would wait for devices when they
were specified as a label or UUID, but would not wait when the user
passed a "/dev" file name directly.  This could cause problems when
the /dev node takes a while to show up.

* gnu/build/file-systems.scm (canonicalize-device-spec): Add 'resolve'
call in the 'string?' case.

file-systems: Handle EIO error in 'ENOENT-safe' as well.

This patch catches and warns in this case rather than dying.

Ludovic Courtès b86fee7848 file-systems: Use a second 'mount' call for read-only bind mounts.
* 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.

宋文武 9331ba5dd9 linux-boot: Make /etc/mtab a symlink to /proc/self/mounts.

* 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

Ludovic Courtès 1c27641f46 file-systems: Always write the options field in /etc/mtab.
* 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.
