Right now I have duplicate users on it and use scp to push files over to it but had a thought...

Could I completely replace /home with my desktop F33 system using iSCSI?

I like this idea for two reasons:

1. I would have access to the identical files on both systems without having to scp files around, including not having to do duplicate "fedpkg clone...".

2. A lot of the time a package is building the CPU is waiting on the SD card even though it's a class 10. I'm betting IO would be faster over my gigabit Ethernet. AND save all the writing to the SD card, extending it's life.

Sure, why not?  Three caveats:

1. iSCSI is extremely sensitive to latency and somewhat sensitive to bandwidth, so make sure they are network "close".

2. The UID and GID will be important in this setup, so make sure that they are the same for the user(s) that you want to have common on the two machines.

3. The selinux policy for the home disk had better be pretty much the same for the two machines.  Any differences between the capabilities on disk will produce strange blocking behaviours.
