mount

Syntax follows standard /etc/fstab format:

Usage: bastille mount TARGET HOST_PATH JAIL_PATH [filesystem_type options dump pass_number]

The options string can include a comma-separated list of mount options, but must include one of (rw,ro,rq,sw,xx) according to fstab documentation.

Example: Mount a tmpfs filesystem with options.

ishmael ~ # bastille mount azkaban tmpfs tmp tmpfs rw,nosuid,mode=01777 0 0
Detected advanced mount type tmpfs
[azkaban]:
Added: tmpfs /usr/local/bastille/jails/azkaban/root/tmp tmpfs rw,nosuid,mode=01777 0 0

Example: Mount a nullfs filesystem

ishmael ~ # bastille mount azkaban /storage/foo media/foo nullfs ro 0 0
[azkaban]:
Added: /media/foo /usr/local/bastille/jails/azkaban/root/media/foo nullfs ro 0 0
ishmael ~ # bastille mount azkaban /storage/bar /media/bar nullfs ro 0 0
[azkaban]:
Added: /media/bar /usr/local/bastille/jails/azkaban/root/media/bar nullfs ro 0 0

Notice the JAIL_PATH format can be /media/foo or simply media/bar. The leading slash / is optional. The HOST_PATH howerver, must be the full path including the leading slash /.

It is also possible to mount individual files into a jail as seen below. Bastille will not mount if a file is already present at the specified mount point. If the jail file name does not match the host file name, bastille will treat the jail path as a directory, and mount the file underneath as seen in the second example below.

ishmael ~ # bastille mount azkaban /etc/rc.conf /mnt/etc/rc.conf nullfs ro 0 0
[azkaban]:
Added: /etc/rc.conf /usr/local/bastille/jails/azkaban/root/mnt/etc/rc.conf nullfs ro 0 0
ishmael ~ # bastille mount azkaban /etc/rc.conf /media/bar nullfs ro 0 0
[azkaban]:
Added: /etc/rc.conf usr/local/bastille/jails/azkaban/root/media/bar/rc.conf nullfs ro 0 0

It is also possible (but not recommended) to have spaces in the directories that are mounted. It is necessary to escape each space with a backslash and enclose the mount point in quotes “” as seen below. It is possible to do the same for the jail path, but again, not recommemded.

ishmael ~ # bastille mount azkaban "/storage/my\ directory\ with\ spaces" /media/foo nullfs ro 0 0
[azkaban]:
Added: /storage/my\040directory\040with\040spaces /usr/local/bastille/jails/azkaban/root/media/foo nullfs ro 0 0
