Bug 216983: emulators/linux_base-c6: info message advises to make the system
not boot properly
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216983



--- Description ---
1. install message for linux_base-c6 tells me to add 2 mounts to /etc/fstab
because some programs might need it:

pkg info -D linux_base-c6
linux_base-c6-6.8_11:
Always:
Some programs need linprocfs mounted on /compat/linux/proc.  Add the
following line to /etc/fstab:

linprocfs   /compat/linux/proc	linprocfs	rw	0	0

Then run "mount /compat/linux/proc".

Some programs need tmpfs mounted on /compat/linux/dev/shm.  Add the
following line to /etc/fstab:

tmpfs	 /compat/linux/dev/shm	tmpfs	rw,mode=1777	0	0

Then run "mount /compat/linux/dev/shm".

2. if I add them just like that and reboot - the system will boot into a single
user mode, because '/etc/fstab' fails to mount those mounts.
3. it so turns out that one needs to add

linux_load="YES"
linprocfs_load="YES"

to the '/boot/loader.conf' file.

4. even with those lines added to the '/boot/loader.conf', the tmpfs mount in
'/etc/fstab' will still lead to booting into a single user mode.

As far as I know (not 100% sure), but adding 'late' option to the tmpfs mount
entry in '/etc/fstab' resolves the issue, but this is not mentioned anywhere
and the port's info message directly advises to add quite specific line to
'/etc/fstab', which leads to system not booting properly.
