[arch-releng] iPXE HTTPS
by David Manouchehri 14 Dec '15

14 Dec '15

On the Arch netboot page, several of the scripts are using HTTP. iPXE supports HTTPS, so I believe there's no reason to use HTTP. https://releng.archlinux.org/pxeboot/arch_text.ipxe Feel free to chime in if I'm missing something. -- David Manouchehri F0FE 0296 14EA 35BC 9E4FF 9768 A6EC FD0C 4083 9755 https://keybase.io/manouchehri/key.asc

[arch-releng] switch too sfs
by MrGreen 14 Nov '15

14 Nov '15

Hi, Recent builds of archsio only have 256Mb of availble space, it used to be 32G under img. Is there a way to either enlarge overlay size (other than cow_spacesize cheat code)? Some installation of extra tools via pacman fail due to no free space on drive.... Mr Green

[arch-releng] reduce image size
by Christian Hesse 07 Oct '15

07 Oct '15

Hello everybody, now that we support root filesystem on squashfs/overlayfs... Do we want to reduce image size some more? Currently we generate a squashfs for each architecture, one for x86_64 and one for i686. How about merging these into one filesystem? Only extra thing to do is a bind mount for the subdirectory to /new_root. The benefit is the deduplication support in squashfs, identical files are added to the filesystem just once. I did not yet test with the official media, but I'd expect the size to shrink about 120MB... This has a drawback, though: Copy-to-RAM would copy the files for both architectures, not just the needed one. Any comments? -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Chris get my mail address: */=0;b=c[a++];) putchar(b-1/(/* gcc -o sig sig.c && ./sig */b/42*2-3)*42);}

Re: [arch-releng] arch-releng Digest, Vol 75, Issue 3

One thing that would be interesting would be auto load to ram, just guessing here but hook could test available ram on system and run from there.

[arch-releng] [RFC] Switch from dm-snapshot to overlay
by Gerardo Exequiel Pozzi 28 Sep '15

28 Sep '15

Hello Guys, what do you think about switching to overlay filesystem by default? This is already implemented around Jan 2015 of this year. Why?: * It seems the most "natural" way. * Low RAM usage if user wants do to some changes inside live-enviroment. * No crazy crashes if zero-free-space is reached (some bbs/wiki talks posts ask about this) There is at least two issues at boot time: (1) /var/log/journal: Cannot set file attribute for '/var/log/journal', value=0x00800000, mask=0x00800000: Inappropriate ioctl for device (2) /etc/machine-id: Failed to unmount transient /etc/machine-id file in our private namespace: Invalid argument (1) Does not care. (2) Unsure about it. The file has an "id" after bootup, maybe the most safe thing to do, is to generate machine-id at build time (or at initramfs), instead of just placing an empty file and generate an "id" at runtime (on switched-root). # hostnamectl Static hostname: archiso Icon name: computer-vm Chassis: vm Machine ID: b0e5ffa9728f421dacf4564936dce6e1 Boot ID: 92e4f6a2202f49798cb0e4782e791daf Virtualization: kvm Operating System: Arch Linux Kernel: Linux 4.1.2-2-ARCH Architecture: x86-64
