Description Kalle Richter 2017-06-04 16:07:50 UTC 
The PPC base installation handbook page suggests to remove `/dev/shm` "When using non-Gentoo installation media [...] [on] some distributions". Since that left me with no idea whether I should remove `/dev/shm` or not, I did it with the suggested command which failed because `/dev/shm` is a directory on my iMac G4 PowerMac6,1. The instructions should be completed to cover this case and and more clarity when and when not to remove `/dev/shm` would be appreciated.

Reproducible: Always

Read the section again:

> Some distributions make /dev/shm a *symbolic link* to /run/shm/ ...

If /dev/shm is not a symbolic link, you do not need to remove it.

I see. If the command/instruction would contain a check for whether `/dev/shm` is invalid link it'd be perfectly clear.
