====== Linux Problems ======

===== NFS won't start =====

In [[https://www.devuan.org/|Devuan]] Beowulf, I installed nfs-common so I could mount some nfs shares, but the mount on boot does not work. After boot is complete, I can mount my nfs shares manually.

Looking in the logs, I see the following error:
**/run/rpcbind not owned by root failed!**

This is caused by an incorrect path (see https://lists.debian.org/debian-user/2018/10/msg01012.html), which can be fixed by the following:

<code bash>echo 'PATH="$PATH:/usr/bin"' >> /etc/default/rpcbind</code>

/etc/default/rpcbind is called in the startup scripts, so this will add /usr/bin to the path when nfs is started.

===== sort gives unexpected results =====

Ran into a problem on Devuan (Debian) Linux where sort did not give expected results.

INPUT: 
<code text f.dat>
02-175CB:D
022C11EE:D
02-2D270:D
</code>

<code bash>sort f.dat</code> returns
<code>
02-175CB:D
022C11EE:D
02-2D270:D
</code>

Run under FreeBSD and also <code bash>perl -e '@a=(<>);chomp(@a);print join($/,sort @a).$/;' <f.dat</code> returns
<code>
02-175CB:D
02-2D270:D
022C11EE:D
</code>
Which I expected.

Under Linux, you can get the same results by setting the collate first: <code bash>LC_COLLATE=C sort f.dat</code>

I tracked this down from a similar problem using //ls// on Linux. See https://unix.stackexchange.com/questions/35469/why-does-ls-sorting-ignore-non-alphanumeric-characters.
