rpc: improve IPC socket error message for filesystem compatibility

cloorc · cloorc · commit 3f25dc5956cc · 2025-11-09T21:01:17.000+08:00
Clarify that ext2/ext3/ext4 filesystems support Unix domain sockets
(including Thunderbolt Type-C drives), while exFAT does not. This helps
users understand why socket creation may fail on certain filesystems.
