Bash completion misconfigured on CentOS 7

[Craig Scott]

I am testing out the bash completion for the cmake snap (still unlisted while I work through the teething problems). I've been following the instructions here to investigate:

    https://forum.snapcraft.io/t/debugging-tab-completion/4198

The bash completion works fine on Ubuntu 18, but testing the same release of the cmake package on CentOS 7 results in completion not working and leaving the shell in a strange state. To demonstrate the problem, I'm using the following initial text on the command line:

    cmake -G Ni

This should complete to "cmake -G Ninja", but on CentOS I'm seeing it appear to do nothing. So I followed the above post's advice and opened a "bash -x" shell. The following snippets from the subsequent investigations appears to show the problem:

    [craig@centos-7 selinux]$ snap run --command=complete cmake 9 9 11 2 " " 'cmake -G Ni' cmake -G Ni
    + snap run --command=complete cmake 9 9 11 2 ' ' 'cmake -G Ni' cmake -G Ni
    /bin/bash: /usr/lib/snapd/etelpmoc.sh: No such file or directory
    ++ printf '\033]0;%s@%s:%s\007' craig centos-7 '~/Projects/selinux'

    [craig@centos-7 selinux]$ locate etelpmoc.sh
    + locate etelpmoc.sh
    /usr/libexec/snapd/etelpmoc.sh
    /var/lib/snapd/snap/core/6964/usr/lib/snapd/etelpmoc.sh

On CentOS, the path to etelpmoc.sh appears to be under /usr/libexec rather than /usr/lib.

The snapd RPM is version 2.39.1

The fix is up for review: https://github.com/snapcore/snapd/pull/7008

[Zygmunt Krynicki (zyga)]

The referenced pull request was merged and snapd was released since. I'm marking this as fix released.
