Hi Roberto,
in principle, there is nothing that prevents always logging in the debug
mode. However, you should be aware that the amount of data being logged
is huge. This has following implications:
- as the logs are stored in ramdisk during installation, the memory
requirements for installation may go up slightly
- the amount of data written to the log may hit the installation time,
especially in 2nd stage (writing directly to disk)
- (probably worst) the log will need to rotate - meaning that at the end
of the installation, the logs from the beginning may not be available
any more
Especially the last one may mean that in the end you don't resolve
customer's problem, but even make it worse for us to obtain the right
part of the log.
HTH,
Jiri

I have a customer who is asking if it's OK to set Y2DEBUG=1 all the time:
When we encounter SLES media problem, one of the first things
SuSE engineers ask us to do is reproduce with Y2DEBUG=1 on
the kernel commandline. We were thinking about always having
this media feature enabled going forward. Can we ask SuSE engineers
if there is any cause for concern in doing this?
