packages installation

Reboot the kernel with the root partition mounted 'rw' instead of 'ro':

1. Reboot

USE TSCONNECT: 2. Interrupt the U-boot when you see this:

 Hit any key to stop autoboot: 

3. Print out the environment variable 'bootargs'

 Zynq> printenv bootargs

bootargs=console=ttyPS0,115200 ip=:::::eth0:dhcp nfsroot=129.57.167.16:/vol/diskless/ArchLinux/armv7-devel/root uio_pdrv_genirq.of_id=my-uio ro rootwait cma=384MB

4. Change the 'ro' to 'rw' (may need to copy in parts)

 Zynq> set bootargs "bootargs=console=ttyPS0,115200 ip=:::::eth0:dhcp nfsroot=129.57.167.16:/vol/diskless/ArchLinux/armv7-devel/root uio_pdrv_genirq.of_id=my-uio rw rootwait cma=384MB"

5. Boot (DO NOT SAVE ENVIRONMENT VARIABLES)

 Zync> boot

6. Login as root (through tsconnect or ssh) to use pacman. Usage:

 https://wiki.archlinux.org/index.php/pacman

7. Reboot when done. OS should come back with root fs in Read only mode.
