Rafał Miłecki 8abefc8896 bcm53xx: sysupgrade: optimize building UBI image ... Use "truncate" to adjust size of existing file instead of "dd" which required creating a copy. This saves space on tmpfs. It may be as low as 2.1 MiB when using OpenWrt default user space and way more (20+ MiB) when flashing vendor firmware. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>		2020-03-21 22:31:35 +01:00
