Filesystem and partitions

Explains the partitions on the filesystem and adds various tips and tricks for working with the Skynode's filesystem

AuterionOS partitions

Mount point	Persistent (reboot/update)	Size	Mount option	Description
/	Yes/No	3GB	ReadOnly	Root FS, can be mounted RW (learn more). Wiped at each update.
/tmp	No/No	1.5GB	ReadWrite	Temporary filesystem
/var	Yes/No	4GB	ReadWrite	Var filesystem. Wiped at each update.
/persistent	Yes/Yes	500MB	ReadWrite	eMMC persistent storage
/data	Yes/Yes	32GB	ReadWrite	SDCard storage

Change root/auterion user password

By default the password for root and auterion user is auterion. You can change it by ssh-ing into your device and run the following command passwd. Your new password will be persisted across reboots and updates. Keep in mind that your password can be overwritten by an update if the artifact has been repackaged with the password option.

Root filesystem mount option

By default the root filesystem is mounted as ReadOnly for security reasons. You can re-mount it as ReadWrite with the following command but note that if you power cycle or reboot your device, the root filesystem will be automatically remounted as ReadOnly.

# Mount Root FS as ReadWrite
mountrw

# Mount Root FS as ReadOnly
mountro

In case you want to persist your choice, you can use the following command:

# Mount Root FS as ReadWrite
ao-root-rw.sh

# Mount Root FS as ReadOnly
ao-root-ro.sh

The effect of the two shell scripts mentioned above will reset after an update.
