Many people, use rc.local on Linux. I don't see any benefit in "trashing it" as "not well supported". Also, this file (rc.local) does not require any special "support" since it is not a part of some broader framework. It's simple and works. It's a flat file which is executed at a particular time in the boot sequence.

Also, rc.local is not designed to require a lot of support (to my knowledge), it is simply a place where system admins can put startup scripts they want to start after the other scripts run:

Quote:
The script /etc/rc.local is for use by the system administrator. It is traditionally executed after all the normal system services are started, at the end of the process of switching to a multiuser runlevel. You might use it to start a custom service, for example a server that's installed in /usr/local. Most installations don't need /etc/rc.local, it's provided for the minority of cases where it's needed
On some versions of Linux, the default
Code:
linux #cat rc.local

used to be:

Code:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0

In addition to the above, for completeness, if you search Google "rc.local" with Linux keywords you get around 833,000 results.

I did not find any "memos" (quick scan) where people were saying "rc.local" is not "well supported".... What support does it need? It's a flat file designed to be edited run as described. How do you "support" a flat file executed at the end of each multiuser runlevel?

Why does it need "support? Inquiring minds want to know Smilie


OBTW, on my ubuntu distro, it's blank waiting for someone to add what they want to it:

Code:
ubuntu:/etc# ls -l rc*
-rwxr-xr-x 1 root root    0 Sep  5  2018 rc.local

rc0.d:
total 0
lrwxrwxrwx 1 root root 17 Sep  5  2018 K01apache2 -> ../init.d/apache2

lrwxrwxrwx 1 root root 29 Sep  5  2018 K01unattended-upgrades -> ../init.d/unattended-upgrades
lrwxrwxrwx 1 root root 15 Sep  5  2018 K01uuidd -> ../init.d/uuidd

(truncated)

In fact, all my ubuntu distributions have rc.local available as a "blank" for sys admins who want to use it. It seems "supported to me" since it is there and blank for sys admins to edit and use.
