which one I can safely removed to lose some weight?

Hi,

after install the b43 related packages, my / become so heavy suddenly, reached 84%.

now

:/lib/modules/3.2.0-1-lina/updates/drivers/net/wireless# ls
adm8211.ko       brcm80211     libertas           orinoco        rtlwifi
at76c50x-usb.ko  ipw2x00       libertas_tf        p54            wl1251

root@dove:/lib/modules/3.2.0-1-lina/updates/drivers/net/wireless# du -sh
141M    .

I wonder above director, which one I can safely remove:

# lspci | grep Broad
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe (rev 10)
02:00.1 SD Host controller: Broadcom Corporation NetXtreme BCM57765 Memory Card Reader (rev 10)
03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

I can keep it, just in case there are some redundant packages to take the place,

Thanks for any advice,

I assume you are talking about some embedded system. Remove the modules under drivers/ except those that are used during normal operation. The list of loaded modules is in /proc/modules.

I can imagine that some modules may or may not be used dependent on the mode of operation (e.g. whether encryption is used), but they are not under drivers/
