Autoinstall how to test for partitions

Tue Jul 27 18:03:37 UTC 2021

In my "early-commands" section for autoinstall I would like to determine if
a partition is present. if so mount it copy off same data to ram and then
umount of course and continue.

How do I do that ? If the partition exists I am OK with this :
   - if [ -e /dev/sda1 ]; then etc....

if the partition does not exist - then I get a crash.

How do I check for partitions - BEFORE trying to mount it  so I dont get a
crash ?

fdisk does not seem to be present or did not work.
