Bug 283078: emulators/linux_base-rl9: missing mount/unmount command
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=283078



--- Description ---
Trying to move from emulators/linux_base-c7 and found that mount(8)/unmount(8)
are missing. At least mount is useful to see from a Linux perspective what is
in mtab because:
root@deblndw013x1j:/compat/linux/etc
# ../bin/less mtab
read error
Press RETURN to continue
root@deblndw013x1j:/compat/linux/etc
# ../bin/cat mtab
../bin/cat: mtab: Operation cancelled

but on a RHEL host I can do:
root@deblndw012x:/proc/self
# cat /proc/self/mounts
sysfs /sys sysfs rw,seclabel,nosuid,nodev,noexec,relatime 0 0
proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0
devtmpfs /dev devtmpfs
rw,seclabel,nosuid,size=16228388k,nr_inodes=4057097,mode=755 0 0
securityfs /sys/kernel/security securityfs rw,nosuid,nodev,noexec,relatime 0 0
tmpfs /dev/shm tmpfs rw,seclabel,nodev,size=25165824k 0 0
devpts /dev/pts devpts
rw,seclabel,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0
