Re: [Minios-devel] [UNIKRAFT PATCH v2 0/6] Move VFS initialization to ukboot

[Costin Lupu <costin.lup@xxxxxxxxx>]

Hi Simon,

We clearly need to come up with a solution for initializing filesystems.
However, these series have to be reworked:
1. You should add your changes once.
2. We should add this init thing in vfscore instead of bloating the
boot.c code.

Cheers,
Costin
