OK thanks for the responses so far. I have followup questions for everyone,
even if you didn't previously respond.
Do you think a graphical rescue environment would be helpful in troubleshooting
system problems?
No, a graphical environment implies too many things have to be working (gfx
drivers etc.),
rescue should be doable in minimal environments (root shell, possibly run in an
initrd rescue image).
Do you think a graphical rescue environment using volatile storage, would be
useful? i.e. similar to a Live boot, by default no changes to the system or
Live user environment would be written to persistent media; e.g. Firefox cache
files and history, or even installing software, would be entirely lost on
reboot from this graphical rescue environment
What would this be useful for?
Sort of using another computer without touching the broken one.
Do you think a mechanism for system snapshots and rollbacks would be useful in
troubleshooting system problems?
No. We should stay away from all the bad ideas done elsewhere.
Do you think a snapshot+rollback mechanism would be more or less useful than a
graphical rescue environment, for troubleshooting system problems?
Both are minimally useful.
The best way to debug problems is booting to a minimal root shell,
with mounted filesystems and network access to get packages.
It used to be "1" or "init=/bin/bash" in grub.
Today it is complicated:
- grub hides itself and is difficult to interrupt
- UEFI gets in the middle
- secure boot is in the middle
- proper system operation requires many things: systemd, NetworkManager, ...
- anything graphical requires daemons left and right: dbus, gconf, key agents,
...
Despite all this, booting a USB rescue image is still the ultimate
way to fix things (especially with chroot).
Regards.
