There were some bugs in autofs scripts which caused a lot of grief in
the industry for a while.

Yes, make similar config on another side, restart NFS, and it should work.

What I have in all my Linux workstations is this:
- in konsole (my favorite GUI terminal) I open a number of tabs. First
one is always reserved for root. I label it root and to use it I normally do
sudo su -
that gives me full root environment needed to manage packages, hard
mount files, ISO images, etc. manually. That way I can easily remember
what I'm doing in each "tab".
- in screen utility I also create first text screen for use as root.
Others are named by function or remote host.
If you are going to rename or change UID or GID it's best to do it in
text terminal, i.e. not under KDE or Gnome for yourself as you'll pull
the rug under your feet. You could create a new user with desired
UID/GID in GUI but you'll need to make different login account name. The
easiest IMO is to do the following:
- Assuming you are at GUI login prompt, don't login, use Ctrl-Alt-F1 to
go to text mode terminal,
- login and become root with 'sudo su -' (ubuntu and some other distros)
- edit /etc/passwd to change UID and GID
<user>:x:1000:1000:user name,,,:/home/<user>:/bin/bash
^^ ^^
- run command pwconv
- edit /etc/group
<user>:x:1000:
^^
- run
chown -R <user>.<user> /home/<user>
to change ownership to all files in users home directory.
- Reboot and you should be able to login as a user with new UID/GID.
If you make a mistake in the passwd file and cannot login anymore,
reboot and use live CD (ubuntu, knoppix, fedora, etc.), to bootup, mount
root partition, edit/fix passwd file and reboot. No need to reinstall.
