now I can't login to root

Post#1 by Bob1414 » 12 Apr 2021, 11:05

I boot from a FAT32 USB into guest.

When I logout and try to then login to root, I drop out to the text screen, then get right back to the graphic screen at the login prompt.

The pwd is still good, as I can su in a terminal

I have restored porteussave.dat from a working backup USB. The contents of /modules is the same for each USB.

Do I need to start from scratch with a fresh USB install (then copy into that porteussave.dat), or can I hopefully try some maneuvers to attempt to fix the problem in place?

What else on the USB changes, besides porteussave.dat and the contents of /modules?

Thanks.

No, but you may need to start with a fresh porteussave.dat file.

If the drive is FAT32 formatted nothing, unless you intentionally save something to it. But save.dat files save lots of stuff. My save.dat is 183 MB full. My changes.xzm module which is files of apps and changes I value and manually backup is 13.5 MB. Maybe your old save.dat file has a changed result of something you haven't run yet on the new drive and it's causing problems.

With your new drive start with a fresh porteussave.dat file rather than your old one. And yes that can be a PITA. To minimize the size of the save.dat usage I use this /etc/changes-exit.conf file.

Code: Select all

# Folders listed in this config file will be saved during reboot and shutdown when 'changes=EXIT:' cheatcode is used.
# Folders starting with '!' are omitted. This is useful if you want to save whole folder except for particular subfolder(s).
# An example is inclued in default config below: Porteus will save whole /var folder except for /var/run and /var/tmp subfolders.
# Other example: "!/home/guest/.mozilla/firefox/c3pp43bg.default/Cache" will skip saving of Firefox caches from guest account.
# Thanks to Rava for suggesting implementation of '!' exceptions.

/bin
/etc
/home
/lib
/lib64
/opt
/root
/sbin
/usr
/var
!/var/run
!/var/tmp
!/home/guest/.cache/thumbnails/normal
!/home/guest/.cache/mozilla/firefox/dxsqumip.default/thumbnails/
!/home/guest/.mozilla/firefox/Crash?Reports/pending/
#/home/guest/.mozilla/firefox/dxsqumip.default/storage/default/
!/home/guest/.mozilla/firefox/dxsqumip.default/datareporting/archived
!/home/guest/.java/deployment/cache/6.0/
!/root/.local/share/Trash/
!/root/.cache/thumbnails/normal
And to check the size the file I use this spaceck.sh script:

Code: Select all

#!/bin/sh
# Add to /etc/rc.d/rc.local_shutdown.  And make rc.local_shutdown executable.
#                                      sudo chmod +x /etc/rc.d/rc.local_shutdown

Do not let all the code scare you, I boot ISOs and different versions of Porteus but the basic code should run for you as is.
