Mounts known external drives at /mnt/<name> via nofail + x-systemd.automount, so they mount transparently whenever connected (at boot or hot-plugged later) and never block boot when absent. Foreign filesystems (ntfs/vfat/exfat) get uid/gid + dmask/fmask so andrew and the dev group always have read/write access. Default drives: seagate (Seagate Backup Plus, NTFS) and aegis (Apricorn Aegis Padlock SSD, NTFS). Imported into pc-base.nix. Co-Authored-By: Claude Opus 4.8 <[email protected]>

There was a problem hiding this comment.
Make this mkEnableOption instead, so it defaults to false and requires an additional line in pc-base.nix to set to true.

Summary
New
externalDrivesNixOS module (imported intopc-base.nix) that auto-mounts known external hard drives at fixed/mnt/<name>mount points whenever they happen to be connected — at boot or hot-plugged at any later time./dev/disk/by-uuid/…), so/dev/sd?renaming doesn't matter.nofail+x-systemd.automount(+ idle/device timeouts): boot never blocks when a drive is absent, the mount point always exists, and the drive mounts transparently on first access whenever present. Auto-unmounts after idle, so it's safe to unplug.ntfs/ntfs-3g/vfat/exfat, which lack Unix permissions) getuid/gid+dmask=007/fmask=117, so user andrew and the dev group always have read/write. Native filesystems (ext4, …) skip these and keep their on-disk permissions.Default drives
