3 Software Configuration
KERNEL=="rtc0", SYMLINK+="rtc"
KERNEL=="i2c-0", SYMLINK+="i2c"
3.5. Time Zone
The default time zone configured on the system image is Europe/London (GMT+0). BIOS operates
with UTC time. So in summer time Debian’s clock has one hour difference compared with the time
shown in BIOS. It is normal behavior. Use dpkg-reconfigure tzdata to change the time zone in
Debian according to your geographical position.
3.6. Create Swap File
Swap file can be created instead of creating a swap partition. To create it execute following steps:
1. create file with count being equal to the desired block size: dd if=/dev/zero of=/var/swapfile
bs=1024 count=131072
2. mkswap /var/swapfile
3. add entry to the /etc/fstab: /var/swapfile none swap sw 0 0
4. reboot and check if /var/swapfile is used by looking at /proc/swaps
debian:~# cat /proc/swaps
Filename Type Size Used Priority
/var/swapfile file 131064 0 -1
